Description

Sodium Docosanoate is the sodium salt of behenic acid, a long-chain saturated fatty acid. This compound serves as a versatile intermediate and functional additive, valued for its surfactant properties and stability. It is primarily utilized in the industrial manufacturing of personal care products, lubricants, and as a chemical synthesis precursor. Our supply of Sodium Docosanoate CAS NO 5331-77-1 ensures consistent quality and reliable performance for demanding B2B applications.

Application

• Cosmetics & Personal Care: Acts as a gentle surfactant, emulsifier, and opacifying agent in creams, lotions, and soaps.
• Lubricant & Grease Formulation: Functions as a thickening agent and soap-based gellant in the production of lithium and calcium complex greases.
• Textile & Fiber Processing: Used as a softener and lubricant in fiber manufacturing and fabric finishing.
• Chemical Synthesis: Serves as a key intermediate or catalyst in organic synthesis and polymerization reactions.
• Plastics & Polymers: Employed as an internal or external lubricant and release agent in polymer processing.
• Detergents & Cleaning Agents: Provides cleaning and foaming properties in specialized industrial and institutional cleaning formulations.
